  3: This page starts the password reset procedure. It works according to the next algorithm:
  4: 1. Display a form requesting the username
  5: 2. When receiving the username via form submission, generate a random verification string which is stored (as a hash) inside a ResetPasswordRequestClass object attached to the user's profile page. If no such object exists, it is created, but an existing object will be reused, meaning that at most one password reset request can be active at a moment.
  6: 3. Send an email to the address configured in the user's profile, containing a link to the second step of the password reset procedure.
  7: 
  8: URL parameters:
  9: 
 10: u = user account sent in the form

 16: #set ($userName = "$!request.get('u')")
